DENTAL CARIES&PERIODENTAL DISEASES DR SAMY I ALAGHA A PROFESSOR&CONSULTANT OF RADIOLOGY
RADIOGRAPHIC EXAMINATION OF DENTAL CARIES • BITEWINGS • PERIAPICALS (PARALLELING TECHNIQUE) • PANORAMA
ABNORMAL SHADOWS SIMULATING DENTAL CARIES 1-Cervical burnout Well defined radiolucent shadow at neck of teeth caused by: a-Anatomical configuration of the teeth b-Variable X-ray penetration of crown,neck&root. It is obvious in increased exposure fs&large metalic restoration
D.D OF DENTAL CARIES • 1-LOCATION • 2-TRIANGULAR • 3-USUALLY AFFECT PREMOLAR
ABNORMAL SHADOWS SIMULATING DENTAL CARIES 2-PERITUBULAR DENTINE This occur after caries and its restoration>>>peritubular dentin in tubules under the restoration>>>normal dentin appear more radiolucent
CLASSIFICATION OF DENTAL CARIES 1-OCCLUSAL CARIES :( in posterior teeth) • Incipient lesions • Moderate lesions>>radiolucent zone in dentine • Severe lesions>>> radiolucent hole in dentine
DENTAL CARIES 2-INTERPROXIMAL CARIES:(Between contact point &free gingival margin) a-Incipient>>>radiolucent notch b-Moderate>>>triangular radiolucency which has broad base at the surface c-Advanced>>>triangle in dentin with base at DEJ D-Severe>>invade more than half of dentine
DENTAL CARIES ROOT SURFACE CARIES: • Age>>>30-60ys • Site>>>Mandibular molars &premolars • Appear as ill defined radiolucency
